Automatic lathe



- N11-ED STA'LIENT OFM? SCHEYEB,

To all whom it may concern Be it knownthat I, EMANUEL SCHEYER, a

' citizen of the UnitedStates, residing at New though lar whic York, county of Queens, State of New York, have invented certain new and useful Improvements in Automatic Lathes, of whichn the following is a specification.

This invention relates to yan automatic lathe capable of doing work beyond the range -of the ordinary automatlc turret lathe, cam controlled. Cam controlled ma- 'ed distance -and of a complicated motion.

The cams become too cumbersome and it is often impossible to give them the formvnecessary for the desired motion.

In such machines although the machine itself may run for Hours, it 1s really repeating the operation over again every few seconds. It is impracticable to make large pieces or pieces of acomplicated shape, al-

numbers should `he wanted, it is ound at present more economical to make on a hand operated turret lathe or an ordinary engine lathe.

-`Instead of uslng cams, I employ a perforatedpaper record for controlling the o`peration of ,my lathe. Unlike the cam, the length of an operation is 'no limitation with a paper record, as' paper can be obtainedin strips of great length, nor does' the complexity of the motion present any diiiculty, the only effect being a greater variation in the way the perforations 'follow each other on the record.

'The'cross slide 'is controlled in its motion h fromha slotted feed shaft .in backv of and running parallel. to the bed of the lathe and the' carriage is driven byv afeed shaft inits -usual location 'in front of the bed. Clutches are used to'cause the engagement and disengagement of the aforementioned shaftswith a power shaft, the-gearing between them and the power shaft belng such that reversals of direction can be obtained by the engagement of some of the clutches. .In order to be able to handle pieces-mounted on the centers or on arbors a turret tool holder with suitable indexing mechanism is mounted on the cross l slide.I As is well-v known to the art, this in- -dexing mechanism: operates upon the tool .holder being moved into a certain predetermined position.V Others' of the clutches bring into playdiierent sets of ygearing whereby the traverse and feed ofthe carriages can be specmwtion of Letten Patent.

or New iloxx, N. y',

AUTOMATIC rumanay the clutches are shifted by levers, one end of the lever being forked over the slidingpart of the clutch and the other end fastenedv to the piston rod of a pneumatic cylinder. As airis admitted on one side or other of the piston in the cylinder, the clutch is thrown into engagement in turn to its mating parts. When the air pressure is equalized on both sides of the p1ston, the leverfis vbrought by springs toits central position 'Patented June14, 1921. Appui-.mon maxime 1, 191s. semi 110.302.504.

disengaging the clutch. The, action of the 4 cylinders is controlled by the perforations of the record, which choose which cylinders are to operate as well as the length of time the pistons are held in any desired position.

The action of the perforated recordis similar to that used in automatic pianos, except that in thisinvention the perforations control the motion of levers instead of operating ther keys.

' Owing tothe fact that, when the clutches controlling the motion of the carriage and cross slide are thrown in by the perforations v of the record,l the carriage and cross slide may overrun or fall short of the re uired motion, a plurality of stops are provi ed to arrest the motion at the, correct places..l In settingup the machine the stops are located at the proper places, as many stops being used as is necessary to provide for the desired motions. The record has certain of its perforations to control 4the action of these stops, a stop being able to arrest the carriage or cross slide only when there is a perfora- 'tion of the record corres ending to itin operation at anytime. T e perforations for the stops are so placed on the record thatva stop` is thrown in before the perforations calling for the engagement of the correspending clutch are out of action, thus causing the carriage or cross slide to be urged Vagainst a stop for a considerable interval of time, thefeed shafts being 'provided with a slippage ,device which permits part of the driving mechanism to` be rotated byv the clutches while'thepthe'r part is-stationar The slippage device is adjusted to have su cient grip to hold for the cutting action of the tools, but will give whn the carriage is arrested by a stop.

Insteadv of using the turret on' the cross .slde. the more usual construction of the au'- tomatic turret lathe can be followed by mounting the turret directly on the. bed in l four feed shaftsin this lathe, controlled inv their rotation .by the perforations of the In the accompanyingdrawings', which are' largely diagrammatic, I have illustrated one practical form in which the invention may be embodied; but it will be understood that the same may be varied considerably in respect to details within the sco e of the appended claims; and referring t ereto Figure 1 is a front elevation'of the machine.

Referring to Figs. 1 to 4inclusive, 1 designates as an entirety the substantially rectangular frame or' housing of the machine surmounting which and extending the major part of its length are parallel V-shaped ways 2 that support -the lathe carriage 3 which is adapted to/Slide along the V-ways 2, .Mounted and adapted to slide on the-carriage 3 lis the cross slide 10 upon which is rotatably mounted the turret tool holder 4.

v The indexing of the turret isaccomplished by, indexin mechanism (not shown) many types of w ich are known to those skilled in the art. This mechanism operates when the. turret is moved past a. predetermined The carriage 3 is drivenby the feed shaft' 12 which operates the usual carriage gearing (not shown). This gearin coperates wit rack 11 and is thereby ena led to move carriage 3 back and forth as desired. Through spiral gears 47 `and 48 (Fig. 4) the shaft 13 operates the cross-slide 10 by means of cross feed screw 49.

The train of connections between shaft 12 and the 'source of power will now be described. Shaft 73 (Figs. 2, 3 and 4) is assista i driven by gear 75 lwhich is belted to the spindle drive mechanism (not shown) exactly as is done'in United States Patent l Number "1,081,396, December .16, 1913, to

W. L. lSIiller, as Vshown in Figs. 1 and12 of said patent and described on page 3 lines 125 to 129 inclusive, of same. Fixed to shaft 73 are two bevel gears 77 (my'F ig. 2) each tively which in turn operate expansion ring clutches lixed to. spiral gears 66, 67, 71 and 72. Two of these clutches are shown at 6 9 and (Fig. l), the clutches for gears 66 r and 67 being similar. These spiral gearszare made fast to shaft 41 in accordance with which expansion ring clutch is operated. The object of this arrangement is to vprovide a means whereby shaft 41and as will be shown, feed shafts 12 and 13 can be given several different speeds of rotation-whereby different feeds can be given to -the carriage 3 and the cross slide 10. l

For the quick traverse motions of the vcarriage3 and cross slide 10,' the main pulley shaft 33 has keyed to it, thev gears 14 and 16. Gear 14 meshes 1with gear 86 normally loose on shaft 41. Gear 16'drive's idler gear 17 which lin turndrives ear 87 also normally looseon shaft 41. T eclutch follower 93, which can be shifted by lever 91 pivoted at 92, operates expansion ring clutchesixed to gears 86 and 87 fastening oneor the other to shaft 41. When gear 86 is made fast,

. Fixed to feed shaft 12 is the slippage device or friction couplin 36. 'Immediately nextto it ,but loose on s aft 12 is gear 34. Pin 38 (Figs. 6 and 7) projects from gear 34 through a hole in lug 39 forming -a part of the band 40 encircling the coupling 36. The rightl amount of friction. grip is obtained 'by means of spring 45 bolt 43 and lock nuts 44.

Gear 34'and hence shaft. 12 is driven from shaft 41 through gear 35 fixed to short shaft 42. The clutchfollower 8 on Ashaft 41-is shifted by lever .26'pivoted at 25 and is adapted to fasten, depending upon its position in a similarr manner to that described for gears 86 and 87, the gears 27 and 23 to shaft 41. Gears 27 and 23 are normally loose on shaft 41. Gear 27 meshes with gear The 28 to drive shortshaft 42 in one` direction and gear 23 through idler gear 37 and gear 24 drives it in the opposite direction.

The mechanism for driving shaft 13 and hence the cross feed screw 49 and cross slide will now be described. The clutch follower 46 on shaft 41 is adapted to be shifted by lever 59l pivoted at 60. Gears 50 and 54 normally loose on shaft 41 are adapted to be 10 ring clutches attached tofthem,` depending upon the position of the clutch follower-46. Shaft 33 carries loose, near its left hand end a s1eeve'61 `having fixed to it gears 51 and 52. When lgear 50 is fastened to shaft 41 it drives the sleeve 61 in one direction by 'means of gear 5-1 and when gear 54 is made fast to yshaft 41 it drives sleeve 61. in the opposite direction, through idler gear 53 and gear 52. At the left hand end of sleeve 61 is sprocket 62 fixed to it. Shaft 13 carries a sprocket 76. loose on it at its left end. By means of link belt 64, sprocket62 drives 'sprocket '7 6. Next to sprocket 76 is the slippage device 65, which is driven from sprocket 76 by means of a pin and friction band similar to that already described in connection with slippage device 36 shown in Figs. 6 and 7. Slippage'device 65 is lfixed to shaft 13 and drives it in accordance with the position of the clutch follower 46.

The various-levers 18, 15, 19, 26, 59, 55,

. 91 and 56 are actuated by the piston rods of the pneumatic cylindersy 83, 84, 85, 88, 89, 90, 109 and 94 respectively, a typical one of which 109 is shown in enlarged detail in Fig. 10. The piston 108 which slides within the cylinder 109 carries the-piston rod 95. vThe other end of piston rod 95 engages with the lower end of lever 91. As thepiston cylinder 109 the lever 91 is caused to shift its. clutch follower 93 into its yopposite operating positions. When airI is exhaustedv through the tube 96, the pressure to the left of the piston 108| is reduced whileat the Sametime air is exhausted throughthe branch tube 106 and to the right of the pist0n inthe small cylinder 100, causing theV piston to bedrawnl in against the pressure of spring-101. yPiston rod 101 has anopening 102 in it, which when drawn into line with tube 99 admits air at atmospheric pressure to the right of piston 108 causing it t0 move tol the left. When air is, exhausted through tube 97 the pressure is reduced to .the right of cylinder 108 while at the same time it is reduced through branch tube 105 to the left of the piston of small cylinder 104, drawing in its rod 103 until theV opening in the rod registers with the tube 98 admitting air at atmospheric pressure to the left of piston 108 .and forcing it to the right.

When air is exhausted neither from tube 96V nor 97 it is caused to-become equzlized on made fast to shaft 41 by means of expansion 108 is forced to one end or the other of theboth sides of the piston through leak hole 107 in the piston. The use of leak holes in pneumatics is well known to the art of automatic player pianos. When no 'air iswithdrawn from either side of the 'piston 108, 70 the lever 91 is soon drawn into its central position by means of levers 110, and 111, and springs 112 and 113. '(Figs.. 1 and 5.) The levers 110 and 111 are pivoted at 115 to a lug from the 'housing 1.. Spring 112 nor- 75 mally holds lever 111 againstlug 114 projecting from the housing 1 and-spring 113 normally holds lever 110 against lug 114, thus maintaining lever` 91 in its central position when not acted .upon by piston 108. A similar arrangement is used to keep-the levers 18, 15, 19, 26, 59, 55 and 56 in their central po sitions when not acted upon by their corresponding pistons.

The perforations of the record 116 deter-V 85 mine which ports of the various lever actuating cylinders 83, 84, 8 5,etc.,should exhaust air at any given time and thus effect the operation of the machine as will now be described. The perforations of the record 116 9o as it unwinds from spool 117 onto spool 118 pass over trackervducts indicated by d1 d, cl3-da in Fig. 1,1. The use and action of a perforated record and tracker ducts 'is well known to-the automatic player piano art and is also fully described in` my United States Patent Number 1,172,059, February 15, 1916 (seel Figs. 6, 7, 10 11 and 12 of said patent). Pulley 119 on shaft 33 by means of belt 120 drives pulley 121 fixed to'shaft 100 122 which is geared byo reducing gearing (not shown) to the .shaft rotating spool 118. Likewise shaft 122 drives an `exhaust pump indicated at N in Fig. 11 in a similar manner to that shown in Figs. 6 and 7 of my 105 above mentioned patent, where the record .mechanism is su-iliciently explained to make it unnecessary to do so here.

Referring to Figs. 1, 4 `and 11 of the present application, the exhaust pump E drivenlllo from shaft 33 is connected by tubes b1, b2-

536 to cylinders c1, 024-039'. Cylinders 01, c2-

manner the other tracker ducts control the 12.0v

connection ofthe exhaust E to the other lever shifting cylinders. In Fig. 11 of the present application it will be fnoticedthat tube al1 has a brancha 'leading to cylinder-` c and duct d", tube a2, a branch als to cyl- 125 inder c and duct d, tube a3, a branch a to. cylinder 021 and duct d, etc. The object -of this is lto prevent the necessity of a continuous slot in the record inthe case where it is desired keep one of the clutch levers 136V I jecting from it the slotted plate 131 in which can be bolted -in various positions the do 127 and 128. More dogs and stops can e used', depending n the number of operations desired. In ya similar manner cross slide carries 'dogs 129 and 130 or more if the carriage which are actuated by a perfoferring now -to F igs.- 8 and9, 124 is the 'stop required.

-The stops 123, and 124 can be adjustably placedl in the slots of plate.132 projecting fromhousing 1. In a Similar manner the stops 125 and 126 are held in plate 133 projecting from carriage 3 (Fig. 4).

The dogs 127 and 128 are adapted to engage the top of stops 123 and 124 and theref by arrest the motion of the carriage. Only those stops are able toarrest the motion of ration of the record at any given time. Re=

i having its upper end beveled and rounded 0a. stop 124 has aslower end bifuratea,

and it swings about a pivot 134supported in upright 146. The piston rod 140 is adapt-v ed to enter the bifurcated lower end of the stop. 124 vandthereby prevent it from turn-v ing about pivot 134. AWhen a perforation of the record comes over tracker duct d it 'actuates the 1piston of cylindei` c1 so that the exhaust is Aconnected through tubes b1 and a1 tocylinder 143 above the piston 142 (Fig. 8) This causes the piston 142 to rise against the pressure of spring 141, normally keeping the gaston 142 at the bottomv v of cylinder 143. en piston 142 .rises it orces'the piston rod 140 into the bifurcated end of stop 124, and now when; the dog 127 comes against sto 124 the-motion of car' riage 3 is -arreste *The record is so -perforated, that `the perforationfor actuating piston 143 is over tracker duct d for a .con-

g site direction .the perforation for actuating siderableinterval of time before the perfora-v tions of the record V'throwing inthe clutch 4follclwer 8 have ceased to pass over tracker ducts i7 and d. For arresting the motion of the carriage when traveling in the oppo- I v'piston 143 is in before the perforations for tracker 'ducts d and d have ceased to pass over them. This allows the slippage device 36 to rotate. shaft 12 until lcarriage 3 is jammed hard against jstop '1-24 when the parts of the device Slip over each other maintaining the 'carriage against the stop as long 4shown in Fig. 28

as' the -perforations for theclutch follower-8 Y pass over their tracker ducts.

In Fig. 11 only 'two stop actating'cylin der-s 143 and 147 are shown, not to complicate the drawing, the otherjstops are controlled in alike manner.. It can' be seenrin Fig. 11 that there are two`v tracker ducts for.

each cylinder, e. g.,'d1 and d for cylinder 143.

When vcarriage 3 passes over a stop, say

124, at any time which is not supposed .to ar-` rest' its motion because there are no perforations calling for its actuation, the piston rod 140 (Figs. 8 and '9) is kept down by its sprlng 141 from the 'slot in the lower end of stop 124. Now as a dog 127 comes in contact with the beveled upper end of stop 124, the stop is rotated about pivot 134, until dog 127 passes clear of it. Springs 135 and 138 normally maintain stop 124 in' its vertical posi` tion in a similar manner to the way lever 91 Fig. 5) is maintained inv-its central or neutral position. The sprin s 135 and 138 normally press against uprig ts 144 and 145 at the lsame timeeng'aging the? pins 136 and A137 projecting from the stop 124. )When air is noVlonger exhausted from ltube a, by

142. The space below piston 142 is mainmeans of leak hole. 149 in piston 142 the i pressure is equalized above and below piston tained at atmospheric pressure by means of the large ports 148. The stops and dogs for l cross Slide 10 arrest its motion andare con-l trolled in a similar, manner to Ithat just de- `v scribed for carriage 3.

Tubes, flexible where necessary, connect the cylinders' c1, c2-c3 near the record with the lever actuating cylinder- 83, 84, 85,

etc., and the stop actuating cylinders 14 3,`

147 etc.

Some of these tubes'are shown 1n the casing 150 (Fig. 2) passing down the back of the lathe, but not elsewhere to avoid confusion.

Instead of using an exhaust pump E by a slight rearrangement of the` valves' a compression pump could be used as explained in my Patent Number 1,172,059..

There are several different types of record that can be .used instead o the perforated paper record. For example an embossed record could used to make and break eleotric circuits (see Fi 29 of my U. S. Patent- Number 1,172,058, ebruary 15, 1916)- and the making and breaking of these circuits could control solenoid actuated valves (see Fig.'v 26 of -my other Patent VNumber 1,172,059) instead of the pneumatically controlled valves c1,c2, etc. of the present application. Alsoa perforated record, -say of brass, could be used to operate mechanism as of my lPatent Number 1,172,059 anddescribed on page 11 lines 21- to 38 inclusive, as well as the method shown in Figs. 25 and 27 of same and described on pages 10 and 11Awith` the exception that assiste the selector mechanism described there is omitted and the valves r1, r2, etc. instead of the cylinders c1, c2 of the present application connect the exhaust E to the lever throwing and stop actuating cylinders of the lathe.

The method of operation is as follows z-Having determined the operations, speeds and feeds necessary for turning out a given piece, .the record is laid out in the drafting room, and the lathe is set up by iixing the tools in the turret and setting the stops and dogs rin their -proper positions. Now as the record reeds, the various perforations control the positions of the clutch followerswhich produce the desired motions of the lathe carriage and cross slide as well as their speeds of feeding and traversing and the desired successive spindle speeds.

The word marke as -used in 'the appended claims is intended to include the idea of being perforated.
